feat: expose search composition state

[nrps9909]

Summary

• expose an optional SearchInfo object from both showSearch.onSearch and the deprecated top-level onSearch
• report { isComposing: true } for IME composition updates and a final { isComposing: false } event on compositionend
• keep ordinary search callbacks on their existing one-argument contract, deduplicate the browser's possible final input event, and avoid a duplicate combobox onChange

This implements the compatibility path requested in #623: controlled search inputs can continue updating their value during composition, while remote-search consumers can skip intermediate requests by checking info?.isComposing and act on the explicit completion event.

Verification

• exact base 29e9ddac1b8eb3dba4a6681d7c886b542a9d7425: the initial composition probe received two ordinary onSearch calls during composition and no usable completion state
• pnpm test: 21 suites, 438 tests, and 21 snapshots passed
• pnpm compile: ESM, CJS, declarations, and Less compilation passed
• pnpm lint: 0 errors; only existing repository warnings
• Prettier and git diff --check passed
• merged the current feat: support search input autocomplete overrides #1250 head into this head in an isolated worktree: merge was conflict-free, all 439 combined tests and 21 snapshots passed, and the combined ESM/CJS/declaration build passed

pnpm tsc with today's unlocked dependency resolution reports seven existing test-only errors because Jest 30 types removed the old toBeCalled* aliases. The production/declaration compiler above is green, and none of those errors is in a changed file.

Closes #623.

AI assistance disclosure: Codex was used to trace the composition event path, design and run the exact-base regression, implement the focused fix, audit open PR overlaps, test the combined #1250 head, and draft this description. I verified the final diff, test results, build output, and signed commit before submission.

Walkthrough

Select 组件扩展 onSearch 的输入法组合状态信息。组合结束时，组件触发一次搜索。combobox 模式的测试覆盖组合文本提交和重复 onChange 场景。

Changes

输入法组合搜索流程

Layer / File(s)	Summary
搜索回调契约与导出 src/Select.tsx, src/SelectInput/index.tsx, src/index.ts, src/BaseSelect/index.tsx, README.md	onSearch 支持组合状态信息。SearchInfo 被导出。README 更新 Select 与 SearchConfig 的类型说明。
组合事件传递与触发逻辑 src/SelectInput/Input.tsx, src/BaseSelect/index.tsx, src/Select.tsx	组合结束事件传递 isCompositionEnd。onSearch 接收 isComposing。组合结束时触发一次搜索。
输入法组合行为测试 tests/Select.test.tsx	测试普通搜索和 combobox 模式的组合事件、结束事件、重复输入事件及 onChange 调用次数。

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to 28c0b

The PR adds optional IME composition metadata while preserving existing search callbacks and preventing duplicate completion events; no actionable merge-blocking risk remains after normal checks and review.
